TRANSFORMER HEALTH PRODUCTS®

Our Components Group in Dallas, Texas, manufactures a group of Transformer Health Products® designed to increase reliability and life of your transformer while lowering the cost of maintenance. Although branded together for the same end result, each of these components offers its own unique functionality.

​2nd Generation Nitrogen Generator

SPX Transformer Solutions’ nitrogen generator produces nitrogen from the air we breathe, providing a continuous, on-demand source of pure, dry nitrogen to protect and maintain the nitrogen blanket on sealed transformer tanks. Notable features include the following:

  • Produces nitrogen at 120 psi instead of the traditional 3000 psi of a standard nitrogen cylinder; lower pressure means less system leaks
  • Maintains transformer tank pressure between 0.2 and 5.5 psi to protect transformer oil from oxidation and moisture absorption
  • Eliminates the need to transport and replace nitrogen bottles and the potential risk of maintenance personnel soft tissue injuries

Inert Air Systems

Using a standard nitrogen bottle, these positive pressure/regulated systems protect transformer oil in the main tank from oxidation and moisture absorption by keeping tank pressure at proper preset lev

​2nd Generation LTC Oil Filtration Systems

Designed to be installed on most LTC models to remove carbon and metallic particles produced during normal LTC operation, our 2nd generation oil filtration system helps keep oil in peak condition with minimal maintenance.

​2nd Generation Auto-Recharging Dehydrating Breathers (ARDB2)

Automatic recharging of desiccant maintains peak drying performance, reducing maintenance costs associated with periodic replacement / disposal of saturated silica gel.

​2nd Generation Positive Temperature Coefficient (PTC) Heaters

Our Positive Temperature Coefficient (PTC) heater automatically maintains an enclosure temperature only slightly higher than the outside ambient temperature without using a thermostat or controls thereby protecting against heat damage and condensation.
